英文摘要Potential bioaccumulation is one of the biggest limitations for silica nanodrug delivery systems in cancer therapy. in this study, a mesoporous silica nanoparticles/hydroxyapatite (msns/hap) hybrid drug carrier, which enhanced the biodegradability of silica, was developed by a one-step method. the morphology and structure of the nanoparticles were characterized by tem, dls, ft-ir, xrd, n-2 adsorption desorption isotherms, and xps, and the drug loading and release behaviors were tested. tem and icp-oes results indicate that the degradability of the nanoparticles has been significantly improved by ca2+ escape from the skeleton in an acid environment. the msns/hap sample exhibits a higher drug loading content of about 5 times that of msns. the biological experiment results show that the msns/hap not only exhibits good bioconnpatibility and antitumor effect but also greatly reduces the side effects of free dox. the as-synthesized hybrid nanoparticles may act as a promising drug delivery system due to their good biocompatibility, high drug loading efficiency, ph sensitivity, and excellent biodegradability.
